Noise Reduction Circuits
reinforcement EMS (Measure of endure noise), allowing implementation of the following
features.
(1) Reduced drivability for high-frequency oscillator
(2) Single drive for high-frequency oscillator
(3) SFR protection of register contents
(1) Reduced drivability for high-frequency oscillator
Noise reduction circuits are built in for reduction EMI (Unnecessary radius noise) and
These functions need setting by EMCCR0 to EMCCR2.
Note: When use drivability reduction function of oscillator, please use in case of
Oscillator

C2
EMCCR0<DRVOSCH> register. By reset, <DRVOSCH> is initialized to “1” and
the oscillator starts oscillation by normal drivability when the power supply is on.
